This invention relates to concrete :railroad ties, andhas for one ofitsobjects to provide a tie of this character embodying novel reinforcingmeans which shall be adapted to prevent the tie from cracking, breakingor crushing under any shocks, Jars or loads to which'it may be subjectedby 'a passingcary or train.l

The invention has fora further objecttoy s provide a tie of thecharacterstated which shall embody rail plates recessed in the' upper surfaces ofthe end portions of the tie fand havinganchors embeddedin the tie-insuch manner as to firmly hold the plates in .1 place.

The invention has for a further object to provide a tie of the characterstated wherein the rail pla-tes shall have serrated portions forengagement by serrated portions of rail clamps secured to the plates bybolts, the engagement between the plates and clamps preventing theclamps and consequently the rails" from having any inward or outwardmove- Inent with respect to the tie.

The invention has for a further object to provide a tie of the characterstated wherein the rail plates shall be provided in the serratedportions thereoffwith keyhole slotsfor the reception of the bolts, theformation of the slots permitting theboltst'o' be readily n applied tothe plate after the application of the plateV to the tie and alsopermitting the quires. f l

The invention has for afurther object to provide a tie of thecharacter'stated wherein the reinforcing means shall have portionsthereof locateddirectly below the rail plates, and wherein such portionsshall` be spaced downwardly from the rail plates sufficiently to arrangesubstantial portions ofthe vtie therebetween, such tie portionsinsulating the rail plates from the reinforcing means and thuspreventing the short circuiting of opposf ing rails, and such tieportionspermitting the formation in the ties of recesses located belowthe rail plates for the reception of the heads of the bolts and to carryolf any water passing through the bolt receiving lslots of the railplates.'y

With the foregoing-and I'other `view, the nature-'ofwhich will, appearathe description proceeds, the invention consists in theconstruction,*combination and arrangev ment of parts hereinafterfullydescribedand claimed, and illustrated in the vaccompanying partlyin horizontal sectionV of a concreterailroad tie embodying my'invention,
